TRY-SQUAREAND BEVEL.

SPECIPECATION forming part of Letters Patent No. 360,161, dated March29, 1887.

(No model.)

To @ZZ whom zit may concern:

Be it known that I, ELTON l). KENDALL, a citizen of the United States,residing at Barre, in the county ofVashing-ton and State of Vermont,have invented a new and useful Improvement in Squares, of which thefollowing is a specification.

My invention relates to improvements in squares; and it consists of thepeculiar combination of devices and novel construction and arrangementof the various part-s for service, substantially as hereinafter fullydescribed, and particularly pointed out in the claims.

The primary object of my invention is to provide an improved square, ofsimple and durable construction, which can be easily and readilyadjusted to mark off bevel or miter joints of any degree of inclinationor angle, and which can also be manufactured very cheaply.

In the accompanying drawings, which illustrate a square embodying myimprovements, Figure l is a side elevation thereof. Fig. 2 is anelevation from one side ofthe stock, showing the blade in end elevation.Fig. 3 is a vertical sectional view on the line a; a' of Fig. 1. Fig. 4is a perspective view ot' the parts ot' my improved square detached fromone another.

Referring to the drawings, in which like letters of reference denotecorresponding parts in all the figures, Adesignates thestoek of myimproved square,whieh is preferably rectangular in shape, with iiatright-angled sides. This stock may be made partly of wood or metal, orpartly of wood and faced with metal, as may be preferred; and it has acentral longitudinal opening or passage, a., therein, one end of thisopening being enlarged, as at a, for a purpose hereinafter described. Aclampingbolt, B, extends through this central longitudinal opening inthe stock, and one end ofthe bolt is exteriorly screwthreaded, as at I),and receives a binding thumb-nut, O, which works thereon to draw thehead of the bolt within the enlargement a of the opening a, for apurpose presently described, a washer, c, being interposed between thebinding-nut and one end of the stock. The opposite end of the draw-boltis provided with an enlarged head,

b', which is formed integral with the same, the outer surface of thehead being rounded to adapt it to be snugly fitted in the enlargement aof the longitudinal opening in the stock, so as to compress or draw thebolt rml y within the stock. The enlarged head of the bolt is slottedlongitudinally to provide two yielding jaws, D, which are thus formedintegral with the draw bolt or iron, and between these jaws is fittedthe blade E of the implement. One of the jaws is provided with atransverse opening, whieh is interior-.ly screw-threaded, and in thisopening works the threaded shank of a thumb-screw, F, which serves tovery tirmly clamp the blade to the draw-bolt.

The blade lof the implement is provided with an angular' portion, E',which is adapted for cutting miter 0r bevel joints of any angle orinclination, and the blade E proper is adapted for squaring purposes,the same as other implements ot' the class to which my inventionrelates.

The washer c is provided with a notch, c, in one edge, in which isiitted a pin or key, O', which has a projecting shoulder, c, which 'fitsor takes over one edge of the stoel: A of the implement, so as toprevent the washer from movement on the draw-bolt when the binding-nutimpinges upon the same in tightening the draw-bolt in the stock.

The blade of the implement is first properly adjusted in the draw ironto the required positition or angle by fitting the same between theyielding jaws, and the thumb-screw operated to clamp the blade againstmovement. The thumb-.nut C is now rotated to draw upon the bolt, andthus retract the head ofthe same within the enlargement a of the stockto cause the walls and edges of the same to impiuge upon the split headof the bolt, and thus force the jaws formed by the said head toward eachother and' upon the blade. lf desired, the blade of the implement can beproperly and accurately adjusted in the jaws before the thumbnut C hasbeen tightened, care being taken that the said blade shall lie at rightangles to the parallel sides of the stock.

The parts are very rigidly and firmly held together, and they can bereadily loosened to permit the blade to be adjusted to the proper ICOposition to adapt the implement to the dilerent angles or positions asrequired by various classes of work.

The operation of my invention will be very readily understood by thoseskilled in the art to which it relates without further descriptionthereof.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. A square having a stock, the draw iron or bolt passing therethrough'and having the clamping-jaws, the blade tted between the jaws, and thebinding-nut fitted on the threaded end of the draw-iron, substantiallyas described, for the purpose set forth. a 2. Asquare having a stockprovided with a central opening, the draw iron or bolt passingthroughthe opening and having the split head forming the jaws, the bladefitted between the jaws and provided with the angularportion or section,and the binding-nut fitted on the threaded end of the draw iron or bolt,substantially as described, for the purpose set forth.

3, A square having the stock provided with a central longitudinalopening, the draw-iron having the yielding jaws, a thumb-screw workingin one of the jaws, a blade fitted' between the jaws and clamped thereinby the thumbscrew, and a nut working on the threaded end of thedraw-bolt, substantially as described, for the purpose set forth.

4. A square having the central longitudinal opening provided at one end'with an enlargement, the draw bolt having the enlarged rounded headsplit to form the yielding jaws, a thumb-screw working in one of thejaws, the nut working on the threaded end ofthe draw-bolt, the bladefitted between the jaws, and a .washer interposedY between one. end'ofthe stock and the nut, substantially as described, for the purpose setforth.

5. In a square, the handle or stock, the draw iron or bolt journaled inthe stock, binding means for holding the draw-iron rigid, andclamping-jaws on the draw-iron for the blade.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
